Martin O'Neill has paid tribute to his Aston Villa side and believes they are good enough to secure a top-four Premier League finish this season. Villa are enjoying themselves in the top flight so far this term, as they currently sit in fourth place two points ahead of Tottenham Hotspur below them and the same distance behind Arsenal in third. Villa travel to Sunderland tonight and will look to pick up from where they left off on Saturday in the fine 1-0 defeat of champions Manchester United at Old Trafford and O'Neill insists there is now bags of confidence in the side. "We've got a bit of confidence about ourselves primarily because we look as though we are dangerous going forward," said O'Neill. Villa will be without Stephen Warnock for the trip to the Stadium of Light after the defender was injured at Old Trafford.
